Not slideware. Every video is a hands-on project — real clusters, real pipelines, real incidents — with a clear path from your first Linux command to a portfolio you can show.
# free courses
Structured decks with every command written out and explained. No signup, no paywall — 2 courses and 30 lessons live right now.
From whoami to a production server
The first stop on the DevOps roadmap. Every tool you will ever touch — Docker, Kubernetes, CI/CD — runs on Linux, and this course teaches you to drive it from an empty terminal to a secured, monitored server you deploy yourself.
From git init to a reviewed pull request
The one tool listed on every DevOps job description. Learn commits and branches until they feel obvious, then work the way real teams do — pull requests, code review, protected branches and pipelines that run on every push.
# hands-on projects
Complete, deployable systems built on the channel — each with the full video walkthrough and the repo to prove it on your CV.
The classic first deployment, done right — launch an EC2 server, build the app, serve it with Nginx, and finish with a custom domain and free SSL.
Run a Dockerized Django app on ECS Fargate — the infrastructure written as Terraform code, with a GitHub Actions pipeline that deploys on every push.
Ship to a real Kubernetes cluster — Terraform-provisioned EKS, a GitHub Actions pipeline with SonarQube analysis and Trivy image scans, plus Slack alerts.
The full production picture — a three-tier app on EKS with Jenkins pipelines, security scanning, GitOps deploys via ArgoCD, and Prometheus + Grafana monitoring.
# build-along series
A hands-on project series that takes one AI application from a single $5 server to a multi-cloud, autoscaled platform — deployed on AWS, Azure and Google Cloud. Model serving, vector storage, traffic management, GPUs, observability and the bill, all built in public.
One server, one model, one public URL — the thing you spend the rest of the series growing.
AI traffic is slow, bursty and expensive. Normal web defaults break it.
Third cloud, then the numbers: cost, cold start, GPU availability, and pain.
# certification practice
28 practice tests and 1341+ exam-style questions, each with a written explanation of why the right answer is right — and why the tempting one isn't. Free, no signup, no timer unless you want one.
